Abstract
Continuous occlusal force in a reduced periodontium causes progressive periodontal destruction, which leads posterior bite collapse and flare out of anterior teeth in patients with advanced periodon-titis. We propose new concept “periodontal-occlusal complex (POC) ”for this process. It is important to remove excessive occlusal force in POC in treatment of aggressive and severe periodontitis such as early-onset periodontitis (EOP) . In this study, we present a new treatment strategy for EOP patients. At first, we performed orthodontic therapy and splinting to restore vertical stop and anterior guidance in occlusion. Then, we regenerated periodontal tissue by periodontal surgery.
